Question

find the circumference.
5 cm
c = ? cm
c = πd = 2πr
use π = 3.14

Explanation:

Step1: Identify the radius

The radius \( r \) of the circle is given as \( 5 \) cm.

Step2: Use the circumference formula \( C = 2\pi r \)

Substitute \( r = 5 \) cm and \( \pi = 3.14 \) into the formula.
\( C = 2 \times 3.14 \times 5 \)

Step3: Calculate the result

First, multiply \( 2 \) and \( 3.14 \): \( 2 \times 3.14 = 6.28 \)
Then, multiply \( 6.28 \) and \( 5 \): \( 6.28 \times 5 = 31.4 \)

Answer:

\( 31.4 \)
